How to disable the OneDrive back up nagging from the account's badge notifications?

Since late May or early June of this year (I don't have an exact date, but the earliest I wrote this incident down was probably in very early June), I have noticed that my account icon in the Start Menu often has a notification badge. As I open it, it reminds me that "I should do a back up of my PC in One Drive", and I immediately close it, rejecting it. And the few times it has appeared ever since, they have been weekly, which... it's all fine... up until a couple of days ago, where the reminder has been appearing at least, once per day (three times in the past four days, more or less corresponding to each session I work with, which makes me arrive to this conclusion) which is now annoying me more, because I could still pass it up if it was at least, weekly... but I already have the same "Make a PC back up in OneDrive!" reminder in the notification center as a 30-days reminder, , the nagging defeating its purpose.

This is all in a local account, by the way. I don't want to connect a Microsoft Account (hence, OneDrive) as I prefer my files to remain local (and I also have my means to back up my things), and it's very obvious to me what Microsoft wants from this, though.

I have been reading that it is so simple to toggle it off (Settings -> Personalization -> Start -> Others (Show notifications related to your account), but does it really work like that? I see that the Notifications thing there says something like "When this is deactivated, necessary notifications would keep showing" (my Windows 11 Home Single Language 24H2 is in Spanish, so, I'm sorry this might not be the accurate translation in English), what exactly does "necessary notifications" even mean, or what even counts as "necessary"?
